Question

1. in the diagram below, identify the type of passive transport- osmosis that is occurring.

type of osmosis
what happens to the cell?

Explanation:

To solve this, we analyze osmosis types (hypotonic, isotonic, hypertonic) by cell-water movement:

First Column (Left)

Step 1: Identify Osmosis Type

If the small cell (e.g., a red blood cell) swells (water enters), the solution outside is hypotonic (lower solute, higher water potential than the cell).

Step 2: What Happens to the Cell?

Water moves into the cell (osmosis, passive transport). The cell swells (may lyse if animal cell, becomes turgid if plant cell).

Second Column (Middle)

Step 1: Identify Osmosis Type

If the cell’s size stays the same, the solution is isotonic (equal solute/water potential to the cell).

Step 2: What Happens to the Cell?

Water moves in and out at equal rates. No net change in cell size/shape.

Third Column (Right)

Step 1: Identify Osmosis Type

If the small cell shrinks (water exits), the solution outside is hypertonic (higher solute, lower water potential than the cell).

Step 2: What Happens to the Cell?

Water moves out of the cell. The cell shrinks (crenates in animal cells, plasmolyzes in plant cells).

Filling the Table (Assuming Common Cell Examples: Red Blood Cells)

Type of Osmosis	What happens to the cell?
Isotonic	No net change (water moves in/out equally).
Hypertonic	Cell shrinks (crenates) as water exits.

(Note: The diagram’s visual cues (e.g., arrow direction, cell size change) confirm these:

• Hypotonic: Arrows into the small cell (swelling).
• Isotonic: Arrows balanced (no size change).
• Hypertonic: Arrows out of the small cell (shrinking).)

Final table entries depend on the diagram’s specific cell/solution interactions, but the above logic applies.
